To all fir/fom it 11mg/ (foncer/nf Be it known that l, lfniioiNANo C. llnic'rsNYnnn, a citizen ot the United States ot .liner-ieu, and a resident ot the eity ol St. lliouis and State ot lllissouri. have invented if'ertain new and usetul improvements in (lil llurnere, ot whieli the tollowing is a speci* Iii'ation.

llie primary object ot the invention is to provide an improved oil burner, whereby the oil is ted thereto by gravity and whielrean be used in connection with furnaces, stoves and the like.

ilnother object oi' the invention is to provide an improved oil burner` whereby all ot the air currents that are admitted to the eoinbustion elianiber ot' the burner are directed on the oil trom (litter-ent points thereby assuringa proper eo-minglinpj ot the Peases arisinn trom the oil.

l still turtlier object ot tbe invention is lo provide an ilnproved nie-,ins tor eooling the parts ot this improved burner from the intense heat, thus preventinpr burning out ot the parts ot the burner.

tltlier and turther i'ilijeets will appeal' in the speeitieation and be speeiteally pointed out in the appended elainls, reference bein;r had to the aceompantingA d rawingra exemplitving' the iiwei'itionq and in wl1ielillilrure l. io a vertical aeetion ot a portion it a 'turnaee Showingi this irriproved burner located above the grate bara.

Centrally arranged in the bowl 8 and en tending upwardly therein is an annular tlangfe 12 in which is formed a passageway 13., and centrally arranged adjacent the lower end oteaid `tla'ngre and supported thereto b v ribs llis a threaded bushing l5, there being passageways 16 termed between said ribs. Mounted in the lower end ot said bushing l5 is a vertically arranged pipe 171, and mounted in the upper end ot said bushing and in eonnnunieation with said pipe 17 ie a hollow stein lil, having' at its upper end a spreader 19,V the passageway 20 termed in said spreader eonimunieating with the top thereofH 'lhis spreader' 19 is ot a mush-room shape and has a plurality ot annular grooves 2l tormedon its upper talee.

ite. the tire han been otarted the air entrained vtrom the aah pit ot the turnaee thi-ouah the open bottom Il@ ot the hour/intr dome are a plurality ot lill() 1, the air currents dividing,some of which will traverse the annular passage 6, and enter the draft tubes 23, the currents `from all of said tubes merging in the doine 22 and discharging on top of the oil spreader 19. The other currents of air will be entrained through the passages 16 and annular passageway 13, and upon leaving said annular passageway 13 will engage against the under side of the spreader and be deflected downwardly through the passageway 32 which is formed between 'the lange 12 and the depending lower portion of the spreader, thereby entering the bowl 3 and travelling on upwardly between the depending wall 8 and the spreader.

The air currents following the passage- 'ways as described will all engage the oil flowing over the top of the spreader since the air currents will be somewhat heated, due to travelling the tortuons passageways, the air Currents upon striking the oil will convert the oil into gases so 'that no oil will drip from the depending portions of the spreader, as the oil travelling over the spreader will be converted into a gas before 1 it reaches said depending spreader ed e.

ihe grooves 21 formed on the upper surface of the spreader will tend to retard the oil in its downward flow and, in as niueh as the air Currents are always traversing the annular passage 6, draft tubes 23 and donie 22, the metallic parts forming said passage- 'way and tubes will be kept in a relatively cool condition so that they will not burn out from the intense heat created in the eoinbustion ehaniber 33 which is formed within 'the depending wall 8.

lt is to be noted that the upper edge 34 of 'the flange 12 is on a plane below 4the upper edge of the top portion 7. This is for the purpose of allowing the oil to travel over said upper edge 34 into the passageway 13, providing oil has been allowed to run while eoinbustion has not been in effect in the combustion chamber. This overflowing oil 'will travel down the vertical pipe 17 to the dri I pan 35. n

Igor preventing the spreader 19 from be- 19, and

ing mounted too closely against the upper edge 34C of the iange 12, a lug 36 is lornied on the underside of said spreader, said lug being adapted to engage said upper edge 34 ozt said flange.

What l elainil and desire to secure by Letters Patent, is

1. An oil burner comprised of a housing having an inner and an outer eireular wall, said walls being joined to eaeh other by a curved top wall toi-ined integral therewith, said inner wall curving inwardlv at its lower end thereby providing a bowl within said inner wall in which the curving of the lower end of said inner wall Yforins` a bottoni to 'the bowl, a tubular extension formed integral with the bottoni of said bowl Yorniing a passageway to said bowl troni therebeneath, an oilspreader extended above said extension having its lower edge extended ou a plane below and on the outside of the upper end of said extension, said walls of said housing forming an annular passageway, said upper wall ot' said housing having a plurality ot' openings, and there being ineansl provided for entraining air currents l'roni said openings ot said upper wall to the top of said spreader.

2. An oil burner comprising a housing open at its lower end, a eireular walled bowl portion Centrally arranged in said housing formed integral therewith, an annular passage way 'formed between said bowl portion and said housing, said housing at its upper end being curved inwardly thereby providing an annular wall depending to Suid bowl portion, said wall being curved inwardly at its lower end and forming a bottoni to said bowl portion, said bowl portion having an opening centrally arranged therein and an integrally foi-ined annular (lange extending upwardly therearound. an oil spreadei urranged above said flange, said .housing at its upper end having a pluralityY ol' openings whiffh are arranged on a plane above the up per edge of said Harige, and a plurality ol' removably mounted down-draft tubes leading:` l'roin said openings ol the top ol said housing to the top ol said spreader.
